ABSTRACT
Objective To analyze and compare the ultrasound elastography (UE) features of various types of cervical tuberculous lymphadenopathy (CTL), and to investigate the value and limitation of UE in diagnosis of CTL. Methods A total of 70 CTL patients confirmed by pathology or diagnostic treatment who were admitted to Shanghai Pulmonary Hospital affiliated to Tongji University from Jul. 2017 to Mar. 2018 were enrolled, and the images of conventional ultrasound and UE of the largest lymph nodes in each patient were retrospectively analyzed. According to the conventional ultrasound classification criteria of tuberculous lymphadenopathy, the lesions were divided into acute inflammatory type (type), caseous necrotic type (typeⅡ), cold abscess type (type III) and healing calcification type (type ). The elasticity score and strain ratio of various types of CTL lesions were summarized and compared. Results There were 24 (34.29%) typeCTL lesions, 28 (40.00%) typeⅡ, 12 (17.14%) type III, and 6 (8.57%) type . The hardness of CTL lesions of typeand typeⅡ was high, with the elastic score being 3-4 (47/52, 90.38%) and the strain ratio being 3-5; the hardness of type III was the lowest, with the elastic score being 1-2 (10/12, 83.33%) and the strain ratio2; the hardness of type was the highest, with the elastic score being 4-5 (6/6, 100.00%) and the strain ratio5. There were significant differences in elastic score and strain ratio among the four type CTL lesions (H=30.756, F=23.177; both P0.001). Pairwise comparison showed that except for the differences between typeand typeⅡ lesions, there were significant differences in elastic scores and strain ratios between the four type CTL lesions (P0.05). Conclusion The value of UE in the diagnosis of CTL is limited. It may play some roles in determining whether there is an obvious granuloma formation in typelesions and the tension of type III lesions.
